Flywheel Lightening

[Dave_IOW]

My ABF flywheel taken down to ~7kg, was fitted (and still is) to 20vT.

Did it not need balancing?

That's the same part number as mine; the latest ETKA doesn't recognise it but it is an ABF flywheel.

Panic over then!
Maybe I was looking at the one still on the diesel engine I have!

Interesting read Brad. (except for DH)

I'm certainly glad he makes the distinction between turbo and NA as they need to react differently.

Think I'll go for a conservative 6kgs.
More interested in making sure its balanced.

Very surprised he has gone so low as that is nearly half original weight.

Do you find you need to give it bit more revs to pull away? As there isn't so much of a mass to keep the engine turning?

I had mine down to ~6.2kilo and never noticed any cons, just pros 

Obviously a new clutch at the same time is good economy

Ive said before in another post in reguards to light weight flywheel. I had mine done from martin (hotgolf) and you will need to rev it more as you have less mass rotation so yes more revs but the car does fly through the rev range

One question does the lightened flywheel stop you from crawling like in a traffic jam i just leave it in say gear 2 with no accelerater pedal pressed and my revs will go down to 1000 would a lightened flywheel stall the engine in this scenerio

Not realy. As im always creaping when stuck in traffic. Only when you got to move from standstill you have to rev it just a tiny bit more
